This article aims to enhance the sound insulation performance of the power compartment of a double-drum compactor,addressing noise issues within specific frequency bands through proposed improvement measures.Utilizing the indirect boundary element method,simulations were conducted on the ventilation structure of the power compartment,leading to the design of a novel double-layer ventilation structure that effectively improves sound insulation within the target frequency range.Additionally,the muffler's structure was optimized using finite element analysis and genetic algorithms,resulting in increased transmission loss in the low-frequency range while slightly reducing transmission loss in the high-frequency range.The optimized muffler features a simplified structure and retains a sound absorption material chamber that enhances high-frequency sound attenuation performance.The research findings indicate that the comprehensive optimization strategy effectively improves the overall sound insulation effect of the power compartment,providing scientific evidence for noise control in compactor operations.
